  • Thermoplastic film with integral closures and reclosable container formed therefrom
    Patent number: 4701358
    Abstract: An improved cast process and apparatus for fusing closure elements, particularly those with thickened bases, to separately extruded film or sheet stock for making containers with integral reclosable closures. The process is applicable to webs of film which contain more than one pair of closure elements. The web is split immediately adjacent the die exit between adjacent pairs of closure elements to achieve a film having essentially erect closure elements and associated ribs should they be included. The process also permits beaded edges along both sides of the film. Improved containers can thus be produced.
    Type: Grant
